What will happen if the United States prints a lot of dollars?
Worry is extremely unwise, and if it is not well controlled, it will lead to a sharp depreciation of the dollar. Under the uncertain background of the financial crisis, this will lead to a slight economic recovery, but it will soon fall. Maybe it's another financial crisis, and the consequences are hard to estimate. The result will indeed be a sharp economic upswing in China (not necessarily a bad thing), but they will pay N times more than us.
